If you want to change some settings in your Eclipse 3.2.x you have two choices: Use the extra settings in your command line, something like eclipse -vm ... -vmargs ... Put the extra settings into the eclipse.ini file, something like: -vm ... -vmargs ... If you put your extra settings into the eclipse.ini file you have to be careful: Do not insert an empty line at the end of your eclipse.ini file . If you do this Eclipse will completely ignore your settings! Cheers, Lofi.
